So I'm 4 weeks 3 days and got my bfp last Wednesday ( (8 days ago) on and off I'm getting a little light headed especially if hot. And omg I'm sweating at night and hot. Has anyone else had this. This is baby no 5 and I had hyperemisis gravidarum by this point on baby no 4 till I was 20 plus weeks. But don't remember dizziness
